Team B.S. tries to wall off a safe spot in the Aris fight with obsidian, then finds that hugging the wall keeps them from being pulled in. Scoti dies fifteen times.
The last spawner goes down and Aris finally shows up, pulling Team B.S. back into the hall and storming them with lightning. Sixteen deaths between them.
Team B.S. goes down the stairs into a lava-floored room, finds creeper spawners hidden overhead and behind a painting, and Scoti falls to a Flaming Golem.
